nons iaoso.

To all whom it may concern:

. Be it known that I, WILLIAM H. ERMEN- TROUT, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented new and useful Improvements in Disinfectors for Water-Closets, of which the following is a specification.

This invention relates to improvements in disinfecting devices for water-closets; and

my invention consists of a device secured to the flushipe of the closet in such a manner that the fzed of the disinfectant is operated automatically by the flushing of the water throi'lgh said pipe.

The invention consists of a cup adapted to contain fluid disinfectant secured to the [lush-pipe and having a .valve the stem of which is automatically operated by the water passing down the flush-pipe, thus delivering a quantity of the disinfecting material every time the flush is operated and at no other time. v,

The device can be set to discharge at each emptying of the flushing-tank an amount corresponding in proportion to the number of gal one the tank contains, and that much, but no more, will be sent through the basin and drain-pipe, leaving the water that remains in the basin and in the trap thoroughly disinfected.

My device is artieularly economical as to the use of the isi nfectant, since it not only applies the disinfectant at the right time and at the right place, but it causes each drop of the disinfecting fluid to do the maximum amount of work.

The invention is more fully described in the following specification, and clearly illustrated in the accompanying drawings, in which Figure 1 shows my device applied to the flush-pipe of an ordinary water-closet. Fig. 2 is a sectional view of the valve and the valve-tube. Fig. 3 is a plan view of the valve.

The numeral 1 designates an ordinary flushing-tank, and 2 the flush-pipe leading therefrom to the basin 3.

Ata suitable distanca 'between the tank and the basin 1 secure device, which device consists of a cup 4, adapted to hold fluid disinfecting material, and a tube leading from the bottom thereof at right angles to the flush-pipe, to which it is secured in any Patented Feb. 5', 1907.

suitable manner. This tube'is formed in two partsa straight portion 5, which is secured to the flush-pipe, and a curved portion or L 6, which connects the portion 5 to the cup.

In the straight portion 5 of this tube I form an internal circumferential le( 'ge or shoulder 7. A hollow plug 8 fits snugly in the end of this tube, and this plug is formed with a valve-seat 9 at its inner end. A valve-stem 10 fits loosely in this plug and carries on its inner end a valve 11, adapted to seat against the end 9 of the plug. The opposite or outer end of this stem 10 is formed with a slot 12. The outer end of the plug is also formed with tWo ears 13. The numeral 14 designates a lever which is pivotally mounted between said ears, its lower end 15 and its upper end 16 being made in the form of a plate lying approximately parallel with angles to its depending end 15. A coil-spring 17 is locate-.1 in the tube 5 and rests against the shoulder 7 and against the rear ena of the valve 11, thus ten ..ing to keep the valve across the path of the water flowing in the flush-pipe.

The ,oischarge of the disinfectant is regulated by the strength of the spring 17. When it is desired to have the liquii flow freely, a comparatively weak spring is used, and in like manner a stronger spring when the discharge is to be limited.

The flow of water down the flush-pipe will ('epress the plate 16 until it assumes the position as shown in Fig. 2,. and this action will force the valve-stem in anl open the valve, allowing the liqui-fi in the cup to pass out threugh the tube anl mingle with the water from the tank. When the Water ceases to flow, the spring will close the valve an all useless (.ischarge of the isinfecting flui-i is stopped. When it-is desired to clean the tube, the cup may be readily removed, thus giving access to the parts.

Having thus described my invention, what I claim is- 1. A disinfecting device for attachment to a water-closet flush-pipe comprising a cup, a right-an led tube leading therefrom into said pipe, a p ug located in saidtube, a valve-seat formed on the en l. of said plug, a valve-stem in saiil plug, a valve adapted to seat against said valve-seat, and a plate pivoted to said the axial line of the valve-stem ani at right seated and the plate 16 in normal position loosely engaging the slot 12in the valve-stem plug, lyin in the path of the water in said pipe and having an angled end operatively connected to said valve-stem.

2. A valve for disinfectant-distributers comprising a tubular plug, a valve seat forme-i on the one end thereof, perforated ears formed on the opposite end, a lever pivend adapted to be engaged by said angled end of the plate-lever, a tubular casing having an internal shoulder and a coiled spring interposed between said shoulder and the end of said valve-stem.

, In testimony whereof I affix my signature in presence of two subscribing Witnesses.
